Cover image for Banking Mobile Application A full-stack mobile
Banking Mobile Application A full-stack mobile banking application built with React Native, Node.js, Express, and MongoDB. The application provides a mobile banking experience with secure authentication, biometric authentication, push notifications, account management, transactions, and backend API integration. The transaction system supports network-aware processing. Transactions initiated while offline are handled as pending and synchronized when connectivity is restored, helping maintain a reliable transaction experience across changing network conditions. The application also provides financial statistics, metrics, and expenditure analysis to help users understand their spending patterns. It supports USD, NGN (Naira), and EUR currency conversion and exchange-rate information. I developed the React Native mobile application, built and integrated the backend REST API, implemented authentication and data handling, connected the application to MongoDB, and deployed the backend for production use. The project demonstrates end-to-end mobile application development, combining a responsive React Native interface, secure authentication, network-aware transactions, financial analytics, currency conversion, push notifications, backend APIs, and database integration.

WSF-Attendance Marking System A full-stack attendance management platform built with React, Node.js, Express, and MongoDB. The system manages members, zones, districts, cells, attendance records, user authentication, role-based access, dashboards, and audit logging. I developed the frontend and backend, built and integrated REST APIs, implemented authentication and authorization, designed the MongoDB data structure, and added automated testing across the application. The platform is deployed with the frontend on Vercel and backend on Render.

Cover image for Kutuku | Cross-Platform E-Commerce Mobile
Kutuku | Cross-Platform E-Commerce Mobile App Concept Built a modern cross-platform e-commerce mobile application with React Native and Expo, featuring seamless shopping, secure authentication, order tracking, and responsive user experiences for iOS and Android. Project Type: Mobile Application (iOS & Android) Product Concept Objective: Design and prototype a scalable, modern e-commerce application that simplifies product discovery, shopping, and order management while delivering a fast, intuitive mobile experience across Android and iOS. Overview Kutuku is a modern e-commerce mobile application designed to provide customers with a complete shopping experience from discovering products to securely placing orders and tracking deliveries in real time. The project explores the complete customer journey from onboarding and product discovery to cart management, checkout, and order tracking while focusing on responsive layouts, reusable components, accessibility, and scalable application architecture. This mobile app serves as a product engineering showcase, highlighting how I approach mobile application architecture, UI implementation, state management, navigation, and backend integration. The Concept Many mobile shopping apps become cluttered as new features are added, making navigation confusing and slowing down the shopping experience. Kutuku explores a cleaner, mobile-first approach that prioritizes: Simple product discovery Fast navigation Clear shopping flows Consistent visual hierarchy Scalable architecture Reusable design patterns The goal was to design an application that feels intuitive for customers while remaining maintainable for developers. The Challenge Building an e-commerce application goes beyond displaying products. Users expect fast navigation, personalized experiences, secure authentication, real-time updates, and a frictionless checkout process. The challenge was to design an architecture that could support multiple shopping flows including product discovery, store management, cart management, order tracking, and customer profiles while keeping the experience smooth, responsive, and easy to scale. The application also needed to support offline capabilities, secure local storage, responsive layouts for different mobile device sizes, and reusable components that simplify future feature development. The Solution I designed and developed a modular React Native application using Expo that combines modern UI patterns with scalable engineering practices. Rather than treating each screen as an isolated feature, I structured the application around reusable components, shared state management, and consistent navigation to ensure maintainability as the product grows. The application delivers a complete shopping experience while remaining flexible enough to integrate additional commerce features, payment gateways, and AI-powered recommendations in future releases. My Role As the sole mobile engineer, I was responsible for the application's architecture, frontend implementation, and user experience. My responsibilities included: Product architecture and feature planning Cross-platform mobile development with React Native and Expo UI implementation from Figma designs Component library development Navigation architecture with React Navigation Authentication flow implementation State management and reusable hooks Local data persistence using SQLite and Secure Store Supabase backend integration Map integration for order tracking Performance optimization Responsive layouts for phones and tablets Core Features Product Discovery Browse featured products, categories, recommendations, and collections through a clean shopping experience optimized for mobile users. Store Profiles Dedicated storefront pages allow customers to explore merchants, browse their products, and follow favorite stores. Search Experience Search products with recent searches, suggestions, filtering, and category organization to help customers quickly discover relevant items. Shopping Cart & Checkout Complete cart experience with quantity management, address selection, order summaries, and a streamlined checkout flow. Order Tracking Real-time delivery tracking with interactive maps, shipment status, and progress indicators to improve transparency after processing payment and purchase. Secure Authentication Account registration, login, verification, and profile management powered by secure authentication and protected application routes. Technical Highlights Cross-Platform Architecture Developed using React Native and Expo SDK 54, allowing a single codebase to power both Android and iOS applications while reducing maintenance costs. Modern Navigation Implemented scalable navigation using React Navigation 7, supporting nested navigators, authentication flows, and deep linking. Secure User Data Integrated Supabase, Expo Secure Store, and SQLite for secure authentication, local persistence, and offline-ready functionality. Interactive Maps Integrated React Native Maps to visualize delivery progress and improve the post-purchase customer experience. Reusable Component System Built reusable UI components and shared utilities to ensure design consistency, simplify maintenance, and accelerate future development. Performance Optimization Optimized rendering, navigation, asset loading, and local storage to deliver smooth interactions and responsive performance across a wide range of mobile devices. Outcome The project showcases best practices in mobile application development, including reusable component architecture, scalable navigation, secure authentication, offline-ready storage, responsive design, and clean code organization. Its modular foundation makes it easy to extend with additional capabilities such as payment processing, push notifications, wishlists, loyalty programs, AI-powered product recommendations, and live order updates.
